2D barcodes / QR Codes?

Yep, I've done it heaps, and with NeoReader for the iPhone its a kick ass way to grab info on the run.

QR Codes rock.

The other cool method is that you can use them on the web to copyright your images / blog without being too obtrusive.

It doesn't matter if they don't recognize the QRcodes on your images, thats because if someone finds an online image of yours and decides to blatantly rip it off you can always show the original with the QR intact and prove its yours.

Another good way to protect images is to use a stenography program that ads your copyright as hex into your image in the first 128 bytes of the file.

That way even if they cut the code off your image, you can then have the image checked and DA DA! there is your website/name/email.

I must try NeoReader. I have iDecode which has never worked for me. I wonder how long it will be until these are more common in Aus. I've heard that in Japan they are everywhere, even on business cards. :)

Same Tom - I have not seen them much in Oz and am keen to have a crack at using them. Must see if there is an iPhone app for them.

I have posted a QR to the R&D blog at work. It's a link to the post.

Is that meta?

That was the name of my post. No really.

I've been using timed screenshots and cropping them to get the QR generated from the FF extension I mentioned above.

I've also been able to change my google avatar to a QR link to my blogspot ranting and raving.

What took me so long?
